hpux操作系统磁带备份与恢复

一.扫描磁带机（注意：定期用清洗带为磁带机做清洗）

ioscan -fnC tape

Class I H/W Path Driver S/W State H/W Type Description

========================================================================

tape 2 0/0/11/1/1.3.0 stape CLAIMED DEVICE HP C5683A

ioscan -fnC tape

Class I H/W Path Driver S/W State H/W Type Description

=====================================================================

tape 0 0/1/1/1.3.0 stape CLAIMED DEVICE HP C5683A

/dev/rmt/0m /dev/rmt/0mn /dev/rmt/c3t3d0BEST /dev/rmt/c3t3d0BESTn /dev/rmt/c3t3d0DDS /dev/rmt/c3t3d0DDSn

二.进行磁带备份

根据磁带类型，放入同类型磁带

/opt/ignite/bin （这个是make_tape_recovery 所在的目录）

make_tape_recovery -A v (默认磁带 /dev/rmt/0mn，此备份为常用备份方式)

注意：如果扫描出的磁盘是 /dev/rmt/0mn ，并且类型是HP，可以直接使用上述命令。

如果扫描出的磁盘是 /dev/rmt/2mn（或者其他），并且类型是HP，就需要指定路径： make_tape_recovery -A v -a /dev/rmt/2mn

-A : 指定要备份整个Root disk / Volume Group

-v : 用于显示备份过程的提示信息

-a:指定路径

备份成功显示信息如下：

NOTE: Could not read the /etc/resolv.conf file.

三.磁带恢复系统

把磁带放入磁带机，把安装光盘放入光驱，

磁带恢复系统，需要用到安装光盘引导，到此步骤，选择 Boot from CD/DVD,Recover from Tape,然后进行恢复
